Spindly Alicante Tomato plants

all my tomato plants are behind and looking spindly this year.  Its been too cold.  They are in my polytunnel, but the temperatures are not much better now than a couple of months ago and they dont like the cold.  Hopefully they will get bigger, but for now they are still producing tomatos so that is something i suppose.

Are they getting more shade than the others or did you use a different compost? I sowed some in late March and another kind (a freebie) in mid-April in my cold GH and all four (can't manage any more than that) are looking fine despite the cold day and night temps and me occasionally forgetting to close the door at night! I sowed them in Verve and put two into 10" pots in Miracle-Gro with feed and water additives and the other two into the GH bed.
